Title: Improvements in or relating to data storage devices
IPC: G11C11/44
Filed: 1966-07-05
Abstract: 1,106,878. Superconductive data stores. SOCIETE INDUSTRIELLE BULL-CENERAL ELECTRIC. 5 July, 1966 [29 July, 1965], No. 30225/66. Heading H3B. [Also in Division H1] A persistent current superconductive data store comprises a planar sheet of superconductor material, e.g. of tin or indium, with ribbonform control conductors, e.g. of lead disposed in planes parallel to it. Coincident currents in two control conductors cause predetermined zones of the sheet, constituting memory elements, where the fields due to the currents are additive to go resistive. On removing the control currents circulating currents persist around the resistive areas. To prevent other zones of the sheet in which high current densities occur, e.g. beneath sharp bends in the contol conductors from going resistive and adversely affecting operation of the store the critical current density of these zones is increased, e.g. by a thickening of the sheet, by using a different superconductor for these zones of the sheet, by diffusing a suitable material into the zones to modify them, or by disposing a further sheet of the same or other superconductor over the zones. The control conductor may be parallel as in Fig. 2 (not shown) or may intersect, Figs. 11 and 12 (not shown), in the vicinity of the memory elements. A matrix of elements with parallel control conductors 11, 12, 21, 22 is shown in Fig. 15 with the areas of increased critical current density shaded. In a modification of this the shaded areas are diagonal strips running between the memory elements.

Abstract: 1320764 Endless belt and roller conveyers; feeding and delivering sheets FARAH MFG CO Inc 22 June 1970 [19 Aug 1969] 30273/70 Headings B8A and B8R [Also in Division D1] Apparatus for feeding sheets to and from a sewing machine comprises a conveyer 4, a transfer device 5 an input conveyer 10 and an output conveyer 37a. The conveyer 4 feeds pocket blanks 2 to a lifting bar 3 under control of a photo-cell 8 so that the conveyer 4 is only energized to move when the photo-cell senses that no blank is present on the lifting bar. An arm 6 for transferring the blanks to conveyer 10 has adhesive tapes 7 which are continuously wound from one drum to another so as to provide a surface which will remove blanks from the lifting bar 3 as their forward edges are lifted into contact with the tape. When the tape is in contact with the forward edge of the blank the arm 6 turns through 90 degrees to place the blank on the conveyer 10 the two stationary positions of the arm 6 being controlled by cam operated microswitches. A wheel 12 can be lowered to trap the blank between it and a roller of the conveyer 10 to detach it from the tapes. The conveyer 10 carries the blank to the sewing machine. To remove the sewn blank from the machine a conveyer 57a is provided. A forcing roller 24 can move downwardly to nip the blank between it and a roller 10c which moves faster than the other rollers in the conveyer so that a thread chain between workpieces is broken. At the end of the exit conveyer 57a a photo-cell 25 detects the arrival of a finished pocket and initiates movement of a stacking gridiron 26 which has bars located between the rollers at the end of the conveyer. These bars are driven by a pneumatic arrangement through a rack-and-pinion 27, 29 so that pockets are deposited on a stack supported on a rack which lowers the stack by a distance equal to the thickness of one pocket for each pocket located thereon.

Abstract: 658,842. Conveyers; shoots and hoppers. BOOTH, J. F., and SMITH, R. K. Nov. 26, 1948, No. 30667. [Class 78 (i)] [Also in Groups II, V and XXIX] A conveyer 17 feeds shredded clay from a mixing plant 16 to a transverse conveyer 19 via shoot 18, the conveyer 19 feeding a number of vertical worm extruding machines 11- 14 (see Group V). Adjacent each machine is provided a plough 22 pivoted at 67 at its forward end and adapted to be moved across the belt to intercept and feed clay to the associated machine in response to a fall in the level of clay in the extrusion cylinder, and to be moved to an inoperative position when the clay in the cylinder rises to a certain level. Pivoted feelers resting on the body of clay in the cylinder operate a valve 63 to admit air to one or other end of a pneumatic cylinder 66 controlling movement of the plough 22 and also to one or other end of a cylinder 76 controlling the opening and closing of a gate 82 at the foot of a shoot 21 leading from the conveyer 19 adjacent the plough 22 to the hopper 41 of the extrusion machine. The shoot 21 is open but may be enclosed at its upper end to enable a mist of oil to be injected for lubrication purposes. A continuously reciprocating pusher feeds the clay from the hopper to the extrusion cylinder beneath the pivoted feelers. Successive ploughs 22, Fig. 1, are arranged to sweep successive portions (as shown, successive quarters) of the width of the conveyer. Surplus clay is returned to the conveyer 17 by shoot 23 conveyer 24 and shoot 26. In a modification employing an extrusion machine having a worm feed from its hopper to the extension cylinder which operates only when the machine is extruding, there is no gate 82, and an overriding control is provided to prevent clay being fed from the conveyer to the hopper when the machine is not working. It is stated that the control devices may be mechanical, hydraulic, electric or combinations of these, instead of pneumatic. According to the Provisional Specification (i) the control mechanism may be set to bring the plough to various positions across the conveyer; (ii) a gate may be used at the foot of the shoot feeding the machine incorporating a worm feed; (iii) the feeding shoot is of semi-circular section.
